Specification of Letters Patent.

Patented Jan. 3, 1922.

Application filed September 14, 1920. serial No. 410,239.

T all w Ito m it may concern Be it known that I, JOSEPH Soss, a citizen of the United States, and residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Lock Constructions, of which the following is a specification, such as will enable those skilled in the art to which it appertains tomake and use the same.

This invention relates to lock constructions and particularly to What are known as knob locks and especially to locks of this class designed for use in connection with the doors of motor vehicles, and the object of this invention is to provide a lock of the class and for the purpose specified with improved means for locking the knob or handle of a door against movement to prevent the opening of the door, said means cooperating with the usual latch bolt of the door; and with this and other objects in view the invention consists in a lock construction of the class and for the purpose specified which is simple in construction and operation and efiicient in use, and which is constructed and operated as hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which Fig. 1 is a side view of a part of a door with a knob or handle mounted in connection therewith and showing my improved lock construction;

Fig. 2 a view looking in the direction of the arrow 2 of Fig. 1 with part of the construction broken away and in section;

Fig. 3 a partial section on the line 3-3 of Fig. 2 and on an enlarged scale;

Fig. 4 a view similar to F' g. 2 wlth parts of the construction in a different position;

Fig. 5 a partial section on the line -5-5 of Fig. 4 and on a reduced scale; and,

Fig. 6 a partial section on the line 6+6 of Fig. 3 and on a reduced scale.

In Figs. 1 and 2 of the drawing I have indicated at- 10 part of a door, preferably a,

motor-vehicle door, in which is mounted the usual latch bolt 11 operated through a knob or handle 12 in the usual manner.

The knob or handle 12 in the construction shown comprises a main body portion 13 provided at its outer end with a downwardly directed hand-piece 14. The inner end of the body portion 13 is provided with a square shank 15 which operates the latch bolt 11.

The body portion 13 is provided with a bore 16 which opens outwardly through the end of said body portion and the inner end of the body portion is reduced as shown at 17 and passes through a retaining collar 18 secured to the face of the door 10 by screws or other devices 19. The collar 18 is provided on its inner face with four oppositely directed apertures or recesses 20.

Mounted in and movable radially of the body portion 13, or the reduced end 17 thereof, are two lock bolts 21 which are normally contained within the body portion but which are'adapted to be projected into two of the oppositely extended apertures in the retaining collar 18. Two levers 22 are pivoted within the body portion 13 as shown at 23, and one end portion of said levers pass into and are adapted to operate in apertures 24 in the abutting ends of the lock bolts 21, and links 25 are pivoted to the other end portions of said levers as shown at 26. The other ends of said links are pivoted to a movable sleeve 27 as shown at 28.

The inner end portion of the bore 16 1s reduced and is provided with two key-ways 29 in which projecting lugs 30 on the sleeve 27 operate to prevent the rotation of said sleeve in the body portion 13 but permitting of the longitudinal movement of said sleeve therein.

A disk 31 is mounted within the bore 16 outwardly of the sleeve 27 and provided with an inwardly directed reduced and threaded stud 32, and the sleeve 27 is correspondingly threaded so that when the disk 31 is rotated the sleeve 27 Will be moved longitudinally of the body portion 13.

A plug 33 is mounted in the bore 16 outwardly of the disk 31 and retained in posi tion by a pin 34 passed through the body portion 13 and engaging an annular groove 35 in the periphery of the plug 33. The outer end portion of the disk 31 is provided with a projection 36 provided with two key receiving notches or recesses 37, and the in-.

with t e recesses 37 of the disk 31 to permit of the rotation of said disk, and the movement f the lock bolts 21, through the levers 22 and links 25 as well as the sleeve 27. The disk 31 is held in position by the plug 33 and the shoulder formed by the reduced .bore' of the body portion.

The operation of my improved lock con--,

struction will be readily understood from the foregoing description when taken in connection with the accompanying drawing and the. following statement. It will be apparent that the lock bolts 21 are retained against displacement in the body portion 13 by the levers 22, links 25 and the sleeve 27, and the levers, links and said sleeve as well as the disk 31 are retained against displacement in the body portion by the plug 33. After the parts have all been assembled 1n the manner shown and assuming the lock to be in itsinoperative position as shown in Fig. 3, the same may be moved into operative position by inserting thekey 39 into the aperture 38 of theplug 33 and rotatmg said key to bring the projections 40 thereof into alinement with the recesses 37 in the, disk parts of the lock mechanism may be returned to their inoperative position by rotatingsaid key in the opposite direction to move the sleeve 27 outwardly, which operation will return the bolts 21 into the position shownin Fig. 3. It will be noted that the outer ends of the bolts 21 are slightly curved as shown at 41 in Fig. 5 of the drawing to correspond "with the periphery of the reduced end 17 of the body portion 13.

It will be understood that I am not necessarily limited to the link and lever construction herein shown and described, nor to the Specific means shown for actuating said link and lever construction, or for moving the lock bolts 21 radially, and various changes in and modifications of the construction herein shown and described may be made, within the scope of the appended claims, without departing from the spirit of my invention or sacrificing its advantages.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is

- 1. A lock construction of 'the class described comprising a plurality of lock bolts mounted to move radially in a suitable support, key-operated means mounted in said 31, after which the key 39 is rotated to move,

of sai support and adapted to move said look bolts radially, said means comprising arsleeve movable longitudinally of they support, and levers cooperating with said lock bolts and pivotally connected with and operated by said sleeve.

2. A knob lock of the class described comprising a suitable knob body portion, a sleeve' mounted to move longitudinally of the body portion, key-operated means for giving said sleeve its movement, and means in operative connection with said sleeve and movablelaterally of said body portion for locking the knob against rotation.

3. A knob lock for doors, said knob comprising a suitable body portion in operative connection with the usual latch bolt of a door, lock bolts movable radially in said body portion and adapted to lock said body portion against rotation when in their 0perative position, a sleeve mounted to move longitudinally of the body portion, key-operated means for giving said sleeve its movement, and means connected with said sleeve and in operative connection with said bolts for moving said bolts radially in the movement of said sleeve.

5. The combination with a latch bolt of a door and a knob for operating said latch bolt, of a lock construction mounted within the body portion of said knob and compris ing lock bolts movable radially throughsaid body portion, means on one side of the door in connection with which said lock bolts op eratefor'locking said knob against rotation,

a sleeve mounted in and movable longitudinally .of said body portion, key-operated means for giving said sleeve its movement, and means connected with said sleeve and in operative connection with said bolts for mov1n said bolts radially in the movement sleeve.
